Results from a brand-new high-energy observatory are rocking the field of cosmology. In particular, a study of more than 5,000 galaxy clusters relieves tension in the standard cosmological model.

The southern constellation Carina contains arguably the best nebula in the sky, along with a host of other fascinating stars and clusters.

Double stars are wonderful, but triples are terrific! Here are 16 trios to enjoy the next clear night.

One of the best parts about the eclipse coming up on April 8th will be the opportunity to share the joy and amazement with others!

By studying the formation and evolution of galaxies in the early universe, researchers seek to test the predictions of our leading theory of cosmology.

The first-quarter Moon passes the Pleiades, then Aldebaran. Cassiopeia stands on end. For the southern U.S., Canopus culminates far under Sirius.

A quasi-satellite of Venus has just received an unusual name.

A James Webb Space Telescope survey known as PHANGS has revealed exquisite, just-published details in 19 nearby galaxies.

NASA’s ground-breaking Ingenuity helicopter, part of the Perseverance mission, comes to a rest on the Red Planet.

The asteroid 2024 BX1 went from a moving dot of light to rocks on the ground in mere hours — and amateur astronomers were critical to both discovery and recovery.

Astronomers have found two different star clusters with an enigmatic source inside. Are these objects neutron stars or black holes?

In a first for Japan, the SLIM mission stuck a pinpoint landing on the Moon. How long the mission lasts depends on whether the solar cells begin charging.

Jupiter shines high, bright, and obvious after dusk. Mercury and Mars glimmer low, dim, and elusive for their close conjunction in the dawn.

The Event Horizon Telescope collaboration has released the image from its second major campaign, confirming the existence of a persistent black hole shadow and a potentially turbulent environment.

Although no total lunar eclipses occur this year, skywatchers can look forward to two “central” solar eclipses — including a much-awaited total eclipse that spans the U.S. from Texas to New England.
